REGULATOR 330B, ANTFREZING DRINKHG FUNTAINS.

Application filed March 5, 1920.

To f/Z whom-'it may concern Be it known that L KnLso h/.lrinoooin a citizen of the United States of America, and a .resident of Cincinnati. in the county of Hamilton and State of Ohio, have invented a new and useful improvement in Regulators for intifreezing` Drinking Fountains, of which the following is a specification.

My invention relates to drinking fountains of the type covered b y United States Patent No. 1.146.946. T he objection to the regulating means of the fountain referred to is that when the device is installed there is nothing to prevent the plumber from crushing the ball valve H employed in such fountains as he turns the pipe G in his efforts to regulate the flow. Also there is nothing to prevent the supply pipe G becoming disengaged from the bonnet fr. resulting in dislocation of the parts of the regulating device.

rlhe object of my invention is to provide a regulator that can be properly adjusted before installation of the drinking fountain and that can be subsequently regulated as desired without any danger of smashing the ball valve employedin such fountains.

Another object is to provide means that will prevent dislocation of the regulator parts.

These and other objects are attained by the means described hereinafter and 'disclosed by the following drawing. in which Fig. l, is a vertical section of a drinking fountain with my invention applied to it.

Fig. 2, is a sectional view of the bonnet on an enlarged scale7 forming a detail of my invention. Y

Fig. 3, is a view on linev 8-3 of Fig. 2.

A supply pipe B is attached to a key A. A regulator D vis adapted to reciprocate in a way c, formed in the key A. An adjustable neck d on the regulator extends through the base of bonnet E and is there engaged by a valve F. The flow passes from the recess e in which the valve F is located. through a central bore in lthe regulator to the way in the key and. then through the supply pipe. The flow is modified by eX- tending the neck into. or withdrawing it from the recess e to greater or less distances.

The key A is attached to the lower end of the supply pipe B and is encased within the chamber e3 of the bonnet E through the upper end of which the supply pipe extends. The lower end o: of the key is open. The

key A has a way a', preferabiy of a. square oblong shape` formed in it. This wa)v coinniunicates with the bore of the suppliv pipe.

The regulator D has a block (Z, of a shape similar to, but slightly smaller than the way a. adapted to reciprocate in 0.. The block (Z is so formed or of such size that it cannot enter the supply pipe.

The vblock is seated in the way a and eX- tends from the lower end rEhe collar Z5 formed on the regulator limits the distance to which the regulator may enter way a. Beyond the collar d5 and exterior to the key is a threaded neck d formed on the regulator. At the end (Z3 of the 'threaded neck (Z is a series of notches (Z2 extending diametrically across the regulator. These notches extend for a short distance along the threaded section of the regulator. A central bore Zt extends longitudinally through the regulator, and communicates with the supply pipe and recess c. formed on the under side of base et, of bonnet E. The threaded neck d engages in threaded passage c extending through base et.

The notches (Z2 connect with bore (Z4. l The recess c is formed in the bonnet E. W'h'en the regulator D is screwed through the base c4g the lower end of the regulator enters the .recess e. A ball valve lf is located in the recess and seats upon the surface (Z3 of the regulator under certain conditions. rlhe bonnet and supply pipe are enclosed within a drinking fountain casing C having a bubbler at the upper endV of the supply pipe B. A foot lever G actuates the spring operated casing H to which is attached a valve operating device K. A valve M is utilized to open Y and close the supply. nozzle N through the operation of the foot lever G and the valve operating device l. The operation of the valve operating device K and of the valve M are the same as eX- plained in Patent 1.146.946.

The operation of the device is as follows When the foot lever G is depressed the valve M is lifted from the supply nozzle N allowing a flow of water to pass through the regulator to the supply pipe and to the bubbler o. Before the water reaches the regulator7 the ball valve F is lifted and seats upon the under surface cl3 of the regulator D closing the lower end of the bore (Z4. The water passes around the valve F, through the notches 032 into the bore dt and then Patented June f3, i922?.

through the supply pipe to the bubhler. TWhen the pressure removed from the lever G the valve M is seated upon the supply nozzle N by the action oli spring,` l). rthe Water in the supply pipe and regulator and in the chamber about the valve M drains roin these sections in a manner Well known, and as eX- plained in Patent 1,146,946. The downward rush of the Water in the supply pipe B forces the ball valve F from its seat upon the sur face d3, speedily draining the supply pipe. The flow of Water is modilied by screwing the regulator D through the bonnet lll so as to expose a greater or lesser portion. of the notches interiorly to the recess c. 1t the loW is to be increased the regulator is screwed so as to extend the notches to a point further Within the recess; il' the flovv is to be decreased, the regulator is screwed to raise the notches above 'the recess and in contact With the threaded sides of the bonnet E. The collar (Z5 limits the extent to Which the section d ol the regulator can be injected into the recess c malvinp; it impos sible to smash the ball valve F. This collar also sets upon the ends a et the key A and prevents the dislocating oit the parts. The regulator can be adjusted, ai'ter the lountain is installed, by turning the supply pipe B, by revolving' the bubbler b as explained in Patent 1,146,946. The bubhler and supply pipe are ordinarily secured to one another, thereby forming' a continuous guide duct or supply pipe for the Water. The pipe B transmits rotary movement to the regulator D by means oie the key A. lli the regulator should be moved in. such direction as would tend to separate it from the bonnet, the shoulder Z5 contactingwith the lower end e oi the key Will prevent such dislocation. lt the regulator is turned in the opposite direction, the collar f/Zl contacting' the shoulder et on the bonnet will prevent the neel: d trom crushing the ball valve F.

Having thus described my invention, what I claim is 1.
